I only recently participate, high rank of course and can receive excellent profits, but not us, who became in place and practically did't really earn a new rank, thanks merit 
I know how you feel mate, but even if you are Jr. member or Member, these rank has a chance to earn big like the other higher rank here, only if the ico project campaign you join has a few participants like in signature campaign, those who partake was only a Jr. member or member only especially if the project reach more than a soft cap, this is also depending on the count of the applicants. The more applicants they have in the signature is the more chances that they could earn small percentage only.
